 near base, apex subsinuate, slightly advanced in the middle ; 

 base nearly straight, sides gently rounded and narrowing to 

 apex, anterior angles a little advanced and obtuse, the 

 posterior acute (about 80°); disc densely punctate, sub- 

 rugosely at sides ; a smooth medial line faintly indicated near 

 base, terminating in a small fovea with two very shallow 

 lateral impressions. Elytra of same width as prothorax at 

 base, and three and two-thirds times as long, sides subparallel, 

 lateral sinuosity scarcely evident from above, serrated near 

 apex, extremity with moderately wide oblique lunation; each 

 elytron shortly bispinose, exterior spine conspicuous; striate-

In form somewhat near longicollis, Saund., in pattern 

 near the australasiae , L. and G., type; but the prothorax is 

 more cylindric than that of the former species, as depicted 

 by Saunders, while the blue coloration is much more vivid 

 than in australasiae. Two specimens sent by its indefatigable 

 captor. Type in the author's collection.

 widely on the sides to beyond the middle, two antemedian 

 pear-shaped maculae, one on each side of the suture, an 

 irregular horizontal anteapical fascia extending to the sides 

 but not reaching the suture ; in the female the subbasal fascia 

 is produced downwards on the disc to meet and include the 

 antemedian spots; antennae and tarsi bronze.
